Such filter device is used in different types of industrial equipment and machine to purify in the industrial equipment
With fluid used in machine, such as process liquids, lubricant and congener.The efficiency of filter device is basically by filter element
The especially filtering material of these filter elements determines.Here, the stability of filtering material and filter element, durability and
Good purification to particulate dirt is conclusive evaluation criterion.Many filter devices are contemplated that so-called reflux washing and filtering
Device, so that each filter element successively can be purified continuously by reflux flusher in continuous filtering operation.Such as
It may occur in which high dirt load (Schmutzfrachten) in water ballast application, the dirt load is in a very short period of time
It mixes filter element and its filtering material and in this regard blocks filter process.Therefore, the reflux flusher and pressure control
The design scheme of device processed is chosen so as to be reliably achieved this in pollution load high in this way when reflux is rinsed
The purification as well as possible of a little filter elements.
Such as a kind of filter device for being initially mentioned type as known to 10 2,011 111 457 A1 of DE.Described known
Filter device in, be periodically loaded with particulate dirt and fluid therefore to be filtered in other words non-screening for original filtering
It is flow in the filter housings of the device for process by filter inlet and the filter element that flows from inside to outside.Quilt in this way
The fluid of purification leaves the filter housings then followed by by the filter outlet of setting in the housing.It is wearing from inside to outside
When flowing the filter element, on the inside to be deposited on the filter element from the particle isolated in fluid stream and purify
Fluid stream radially observe and cross the filter element from inside to outside.Typically, it is empty to save structure for the filter element
Between be arranged in filter housings with circular shape and have can be predetermined filtering fineness, the filtering fineness specifically with
The size of particle to be separated matches.
In order to which reflux rinses a filter element, the rinse arm of the reflux flusher is filled by the center driven being arranged thus
Setting can be pivotally moved to below the lower openings of filter element to be clean, wherein the opening being previously mentioned is in other cases
For supplying non-screening during original filter process.Due to being rinsed in filter inlet and the reflux being connected in rinse arm
